Just the lower leaves have damage right now but both plants have turned a lime green coloris it just a few lower leaves, or is there damage showing on newer top growth?
Even with adding nutes?It is normal For MJ leaves to start turning yellow as harvest time approaches... see how it develops.
Even with adding nutes?
Awesome to hear lol its my first grow so don't really know what to expectit's not light burn, so my first person of interest, rather than suspect, is pH level - if it is an issue.
yes.. plants suck up all its nutrients/energy, and yellowing of leaves from bottom to top is typical of flowering growth, towards harvest.
What would curled down leaf tips and some burnt tips suggest?it's not light burn, so my first person of interest, rather than suspect, is pH level - if it is an issue.
are some of the leaves curled downwards, and some burnt tips?

Yes i always make sure theres at least 20% runoffDo you water until at least 20% run-off?
It could be the ph level of the soil. Im watering at 6.2 mainly. Just bought a ph reader and calibrated it a couple days agoAwesome to hear lol its my first grow so don't really know what to expect
I was thinking either a manganese or potassium deficiencyYes i always make sure theres at least 20% runoff
Thats what i was just thinking was a nitrogen deficiency with a potassium and or manganese deficiencyIn something like Fox farm you only want to water until you see some runoff but you don't want something like 10-20% just enough to know the pot is completely watered. These are organics nutrients and if you water to runoff you are washing the nutrients out of the soil. Which is what we do when using inorganic salt fertilizers and why we do it. Organic nutrients need to be treated differently or you end up washing out your nutrients sooner than otherwise.
To me it looks like the nutrients are depleted and you need to start feeding. The burnt tips can be from excess calcium or the beginning of a potassium deficiency.
Now that the nutrients are depleted and your using inorganic you will want to water to runoff. The maxibloom and cal mag create a ratio very low in nitrogen. I suggest a feed with 50/50 maxibloom/maxigrow. For the next couple feeds then 75/25 bloom/grow.
You have a nitrogen deficiency
